Which Non-Hogkin lymphoma is associated with EBV?
Burkitts lymphoma
- Sporadic: 30%
- Endemic: 95%
- Immunodeficient: 24-40%

- Follicular lymphoma - Low grade
- Mantle cell lymphoma - Low grade (More aggressive than FL and CLL)
- CLL/SLL: Low grade
Histo findings of Burkitt Lymphoma
Starry sky pattern
basophilic cytoplasm
round nuclei
Histo findings of FL
No tingible body macrophages (homogenous tumor)
Neoplastic follicles in lymph node cortex or medulla (not just cortex)
Histo findings of Mantle cell lymphoma
larger than normal lymphocyte
Histo findings of CLL/SLL:
lymphocytosis (in bm/lymph node) > 3 months
Prolymphocyte
Lymph node effacement
proliferation center replace germinal center

Which Non-hodgkin lymphoma displays a starry sky pattern?
Burkitt lymphoma
